1. 1. Species interactions in streams - effects of predation, competition and ecosystem properties

   Författare :Erika Nilsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; behaviour; species abundance; stable isotopes; habitat complexity; niche width; niche overlap; competition; streams; predation;

   Sammanfattning : Stream ecosystems are dynamic and they have an inherent environmental variability. Organisms that live in streams are adapted to the continuously changing environment and the presence or absence of species are determined by their environmental requirements, while abundance is most often affected by interactions, such as competition and predation, with other species that are found in the same habitat.

5. 4. Predictors of Alcohol Misuse : Role of MAOA Genotype, Methylation, Transcription, and Negative and Positive Environmental factors

   Författare :Megha Bendre; Kent Nilsson; Erika Comasco; Ingrid Nylander; Mia Ericson; Uppsala universitet; []
   Nyckelord :Alcohol; AUD; MAOA; methylation; expression; early-life stress; maltreatment; parent–child relationship; gene–environment interactions.; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Alcohol misuse is a risk factor for alcohol use disorder (AUD). Gene-environment interactions contribute to the risk or resilience for AUD. A functional polymorphism in the promoter of the monoamine oxidase A gene (MAOA-uVNTR), in interaction with negative environment (Eneg), is associated with alcohol misuse and AUD. LÄS MER

7. 5. Problematic Gaming and Gambling among Adolescents
